Abstract

Extracting conditions of flavonoids from cactus by ultrasonic wave was studied.At first,the suitable levels of ultrasonic power,extracting time,ratio of material to solvent and ethanol concentration were determined using one-factor experiment,and secondly orthogonal design was used to optimize the extracting condition.The results showed that the optimum conditions were power 360W,time 25min,ratio of solvent to material 20/1,and 90% ethanol.On these conditions,the yields of flavonoids was 0.91%.
